Be it known that I, JOHN W. SMITH, acitizen of the United States, residing at Aurora,

--in the county of Buchanan and State of Iowa,

ave lnvented a new and useful Oarbureter, of which the following is a specification.

This invention relates to Improvements in means for vaporizing hydrocarbon oils,`such as gasolene, prior to the delivery thereof into an explosive engine'.

The principal object is to provide an exceedingly simple above character that is effective in operation, is economical and not wasteful, can be readily manufactured, is composed of a comparatively small number of parts, and .is so constructed that it is not liable to become deranged or inoperative.

In the accompanying drawings Figure 1 is a side elevation of the preferred embodiment of the invention. Fig. 2 is a similar view taken at right angles to Fig. l. Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 2. Fig. 4 is a vertical sectional View on the line 4-4 of Fig. 1.

Y Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a body 5 is employed that is in the form of a single casting, said body having a` hydrocarbon reservon 6, and an air conduit located alongside the same. The reservoir 6 is provided with a removable cap 7, preferably threaded thereon, and havinga nipple 8 provided with a vent 9. A pipe 10, leading from any suitable source of hydrocarbon supply, extends through the bottom of the reservoir, and projects upwardly within the same, and' an overflow pipe l1 also communicates with the interior of the reservoir above the bottom thereof.

The air conduit above mentioned is in the form of an elbow, having an upright inlet arm 12, and a horizontally disposed arm 13, the latter projecting beyond one side of the reservoir, and being p 14, whereby it may be readily attached to an engine. A substantially T-shaped hydrocarbon conducting pipe is'located centrally and longitudinally within the air conduit, said pipe comprising an elbow formed of anlgularly disposed arms 15 and 16, the former eing located within the arm 12 ,of the air offset lower end 17 conduit, yand having an lower portion of the communicating with the and novel structure of the.

pipe 11.
